Your question is confused. A galvanometer is an instrument, it is not hooked to an instrument. It is hooked to an electrical circuit of some kind, to measure how much electricity is flowing.
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
Some examples of galvanometers include moving-coil galvanometers, moving-magnet galvanometers, and digital galvanometers. These devices are used to measure small electric currents through the deflection of a needle or pointer on a scale.
The bassoon.
The doctor had to flip back their upper eyelids with a hooked instrument to examine the eyeball for disease--Trachoma. A common instrument was the buttonhook.
The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale. The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)
AC and DC Dynamo, galvanometers, etc...
It is usually hooked up at the column by a clip and string.
Galvanometers were originally used to find the current and thus find the resistance.
To produce a constant torque on the coil
no, it has two degrees of freedom. because it can rotate through X,Y plane.
Hooked on You was created in 2007.
Vibration galvanometers utilize the principle of a coil suspended between the poles of a permanent magnet. When a current flows through the coil, it experiences a force due to the magnetic field, causing it to vibrate. This vibration is proportional to the current passing through the coil, allowing for measurement of electrical currents.
